IMPROVEMENT -IN FUMIGATORS.

Specification forming part of Letters Patent No. 189,915, dated April 1877; application filed March 3, 1877.

To all whom at may concern:

Be it known thatI, GEORGE T.BLANCHARD, of Plymouth, in the county of Penobscot and State of Maine, have invented a new and Improved Fumigator, of which the following is a specification:

Figure 1 is a side elevation of my improved fumigator, in section, on line 50' w in Fig. 2. Fig. 2 is a plan view. Fig. 3 is a transverse section on line g y in Fig. 1. Fig. 4 is a detail view of the grate.

Similar letters of reference indicate corresponding parts.

The invention will first be described in connection with the drawing, and then pointed out in the claim.

In the drawing, A is a bellows of ordinary construction, having the valves or b. B is a chamber containing a central perforated tube, 0, in the bottom of which is placed a perforated diaphragm or grate, 0, which is sup-.

ported by the curved strips d. A pipe, D, connects the lower end of the tube 0 and the bellows A. The upper end of the tube U extends above the top of the chamber B, and is stopped by a cork, 0. An aperture is made in the bottom of the chamber B, which is closed by a cork, f. A nipple, E, projects from the side of the chamber B for receiving the flexible tube F, which terminates in the nozzle G.

The manner of using the fumigator is as follows: A burning coalis placed on the grate c, and the tube 0 is wholly or partly filled with fulnigating material, such as tobacco or sulphur, and is. stopped bymthemorkwe. The bellows is worked, and the smoke issues through the perforations of the tube 0 into the chamber B, where it is cooled, and from whence it passes through the flexible tube and the nozzle. i

Ashes and dust that accumulate in the chamberB may be blown out through the aperture in the bottom by removing the cork f and working the bellows.

Thefumigator is mainly designed for use in killing lice and ticks on sheep and other
